Just wanna ask, what are the common questions of the End User regarding the usage of Accounting Module? I am just curious.

I really want to learn the accounting module , but then, it's so large I don't know where to start hehe. That's why, I wanted to know the most frequent questions/concerns of the End User.. (Accountant)

This site is the main place to look for questions and answers. Since site is few days old questions there are few questions.
Please take a look at the right column of the page and you will find a Documentation block you will find link for the books.

"Open Source Accounting with OpenERP" is the one you should read first.

Online documentation at URL doc.openerp.com/v6.1/index.html is also nice.
